I took the chance to look at the guts of one of my favorite projects: Mozzi. The major starting point is MozziGuts. Just tried to understand what code is relevant and my head started spinning… There is even an expression for this: #ifdef Hell. To make things more comprehensive, I Read more…
Im my last couple of Blogs, I have demonstrated how we can use the low level API of my Arduino Audio Tools library. Currently I am busy working on a high level API using Arduino Streams. I did not commit my latest changes yet but I want to take the Read more…

In this Blog I am giving a little bit of background on how the sampling of analog signals has been implemented in my Arduino audo-tools library. My initial approach was based on the Blog from Ivan Voras using timers and interrupts. But there is a much better way by using Read more…
Please note that a lot has changed since I published this Blog! Tought it might be possible to make this work again, you are advised to use the current API with this updated example! The processing of files with the help of the ESP8266Audio is a little bit more involved. Read more…
In my Arduino ESP32-A2DP library I am providing some very simple examples that show how to transform the ESP32 into a A2DP source and transmit sound to a Bluetooth Sink (e.g. some Bluetooth Speakers). I had quite a few questions on how to do this with files, microphones and I2S Read more…

Today I published the new 1.2.0 Release of my ESP32-A2DP Library. It contains the following improvements: Metadata support with the help of a callback function – Thanks to JohnyMielony AVRC command support thanks to PeterPark Improved init_bluetooth checks, in case bluedroid was already initialized elsewhere – Thanks to Antonis Katzourakis Read more…
I am quite enthusiastic about the new Raspberry Pico. However I find the C SDK not very friendly and I prefer to have something as simple as the Arduino API. I did not want to wait for the official Arduino support – so I started my own project. The last Read more…
